Abstract
This paper proposes a new device for magnetic field sensing that integrates a magneto-elastic rod as active material, with a Fiber Bragg Grating (FBG) strain sensor. Due to rate independent memory effects of the material, the response of the device is hysteretic and this lowers the device accuracy. Accurate modeling of material allows to embed in the device an algorithm for fast compensation of hysteresis so, yielding to a practically linear response of the sensor.
